Indian Prime Minister Narendra Modi landed in Warsaw on Wednesday for a historic visit to Poland before traveling on to Ukraine later this week to campaign for a “peaceful resolution” of the Russia-Ukraine war.

Modi will be the first Indian premier to visit Ukraine and first in 45 years to travel to Poland, Ukraine’s staunch ally and neighbor, and a key transit for foreign leaders heading to Kyiv.

He is expected to meet with Polish Prime Minister Donald Tusk and President Andrzej Duda on Thursday, as well as with Indian nationals living in the Central European country.

Poland “needs a lasting partnership with India,” deputy Prime Minister Wladyslaw Kosiniak-Kamysz told reporters before Modi’s visit.
